Eremophilanes and Pyrrolizidine Alkaloids of Senecioneae Species
Keywords:Senecioneae, Senecio, Roldana, eremophilanes, pyrrolizidine alkaloids
The chemical study of two species of the tribe Senecioneae afforded two eremophilanes and two pyrrolizidine alkaloids from Senecio subauriculatus and four modified eremophilanes from Roldana oaxacana. The chemistry of these species is in accord with that reported for species of Senecio and Roldana studied so far, and therefore, with the already described for the tribe Senecioneae.
